The effect of offspring factor on cow milk components having economic importance
Paper Details
Abstract
The study was performed in order to learn the effect of offspring factor (birth type and sex) in dairy cows on milk components having economic importance such as fat and protein. Milk samples were collected from 24 Red Holstein cows. Milk samples for once were collected from dams in first week of postpartum period. According to results of study, sex of offspring doesn’t have an influence on milk components having economic importance. However, it was found that birth type (single or twins) had a significant effect on milk fat rates. It was found that milk fat rates of dams having twin calves were lower than that of dams giving birth to singles in postpartum period.
